3.3.2 Communication between Nodes

WDM equipment has no channel for transmitting network management information. It
must access the NM information to the transmitted user subscriber signals through a
specified interface to implement transparent transmission of the information.
On the other hand, the NM information of the ZXMP M600 is transmitted to the
subscriber signals through AOSC and BOSC interfaces on the NCP board. The
In Fig. 3.3-2, the data between CWDM node 3 that serves as a non-access node
and the EMS is taken as an example to describe the data report flow. Here, the
report from CWDM node 3 is transferred to the aggregate overhead of the SDH
equipment through the Ethernet interface of SDH node 3. It is then sent to the
access node SDH node 4 and further to the EMS server through the HUB.
